BACKGROUND

1. Field

This invention relates to a method and system of providing a mattressand more particularly, to a mattress using a plurality of foam springsto provide comfort and support to the user of the bed.

2. Background

Consumers, manufacturers, and distributors may each individually or asgroups have many different opinions of the type of a bed and bedfirmness that may provide for a comfortable resting or sleepingcondition. There are many different types of beds and firmnesses tochoose from when deciding on a bed to purchase. In an attempt to provideusers with comfortable beds, bed manufacturers may use metal springs,foam layers, solid foam blocks, water, air, or other means to providevarious types of firmness to a user. These different types of beddingmaterials may be used individually or in combination. Beds may beavailable in various firmnesses using a combination of springs, foamsand materials in various combinations may provide for firmer or lessfirm support to the user. However, even though great effort has beendedicated to making a mattress that provides good support and comfort,the present solutions are inadequate and a need exists for an improvedmattress.

SUMMARY

An aspect of the present invention relates to providing a mattresswherein the mattress has foam barrels or springs on its interior toprovide support and comfort to a user. In embodiments, the foam barrelswithin a mattress may be provided with varying degrees of firmness. Forexample, one region of the mattress may be populated with barrels thatare more firm or resilient with respect to other barrels within themattress. In embodiments, foam barrels of varying firmness may be placedwithin a given region of the mattress. It is envisioned, for example,that one side of the mattress may be set to a ‘firm’ user setting byusing more resilient foam barrels on the ‘firm side and another side ofthe bed may be set to a ‘soft’ user setting by using barrels that areless resilient in the ‘soft’ side. Regions of the mattress may besimilarly adjusted. For example, the areas in the region of a person'slower back may be set to be more firm or less firm by populating thelower back region with appropriate foam barrels. Other such regions ofthe mattress could be targeted for firmness adjustment (e.g. regionsaround the head, neck, upper back, mid-back, lower back, torso, gluteus,upper leg, mid-leg, lower leg, etc.).

Another aspect of the present invention involves providing adjustablefirmness mattresses through the use of varied firmness foam barrels.Embodiments involve providing user interfaces to allow a person toselect firmness settings and manufacturing techniques for setting themattresses firmness per the user requests. In embodiments, the barrelsmay be positionable by a manufacturer, distributor, delivery/set-uppersonnel, the user or other person.

Another aspect of the present invention involves establishing categoriesof mattress firmness types and then providing the firmness types throughthe use of foam barrels. For example, a firmness type may be any one ofthe following: single firmness, dual firmness zones or sides,multi-firmness regions and the like. Each firmness type may beestablished to suit a particular population segment (e.g. firm on sideone and soft on side two) and mattresses may be manufactured per thefirmness types using the foam barrels such that a product offering oftypical mattress types can be made. In embodiments “zoning” or “pattern”configurations for large “groups” of users are determined and mattressesare made using foam barrels according to the configurations and they aremass produced. A user may determine which type of zoned or patternedmattress best suits their particular needs. In embodiments, planningsystems are provided to help users determine, via software or some othermethod, what pattern best suits their comfort needs.

In an embodiment, the foam spring 108 may have aheight that may equal to the height of the mattress outer case, may be aportion of the height of the mattress outer case, may have a heightgreater than the mattress outer case, or the like. In an embodiment, thecross section of the foam spring 108 may have any shape that may includea round shape, a square shape, a hexagon shape, an octagon shape, a starshape, an oval shape, or the like. In an embodiment, a plurality of foamsprings 108 may be contained within the mattress outer case. Theplurality of foam springs 108 may be all the same shape, a combinationof shapes, or the like. In some cases, the foam spring 108 shapes may becombined to provide for spaces between the foam springs 108 that mayallow the foam springs 108 to have freedom of motion. For example, theplurality of foam springs 108 may be all circle shaped or a combinationof circle and oval shaped foam springs 108 to provide spaces between thefoam springs 108 to allow motion areas for the foam springs 108. Inother cases, it may be desired for the foam springs 108 shapes to beselected where the foam springs 108 are in close contact with each otherto allow each of the foam springs 108 to support the adjacent foamsprings 108. For example, the plurality of foam springs 108 may be allsquare foam springs 108 that contact adjacent foam springs 108 on allfour sides; this may provide support to the foam spring 108 and all theadjacent foam springs.

In an embodiment, the plurality of foam springs 108 contained within themattress outer case may have a plurality of different firmnesses. In anembodiment, the foam spring 108 firmness may be defined by anindentation load deflection (ILD) value, indentation force deflection(IFD) value, foam density, or the like. IFD, and in a similar mannerILD, is defined as the amount of force, in pounds, required to indent afifty square inch, round surface into a foam material a certainpercentage of the foam material total thickness. IFD may be specified asthe number of pounds at a specific deflection percentage for specificheight foam. For example, the IFD for a certain foam may be defined as25 pounds/50 in² at a 25% deflection on a four inch thick piece. In anembodiment, the IFD may be influenced by the thickness of the foammaterial, the size of the material, and the like. For some types ofmaterials, such as latex foam, the ILD value may correlate with thedensity of the material used. For others, the ILD may be less dependent,or even independent, of the density of the material used.

The firmness may also be measured or described by the density of thefoam, in pounds per cubic foot, kilograms per cubic meter, or some otherrelevant standard. Although the density may not be a direct measurementof firmness, it may have a direct relationship to firmness. For example,a 110 kg/m3 density barrel may be firmer than a 95 kg/m3 barrel and the95 kg/m3 barrel may be firmer than a 80 kg/m3 density barrel, and thelike.

In an embodiment, the plurality of foam springs 108 may be configuredwithin the mattress outer case to provide localized variable firmnessesfor the bed facility 102. In an embodiment, the firmness of a bedfacility 102 may be varied to provide comfort for a user that may beexperiencing discomfort as a result of an accident, arthritis, surgery,chronic conditions, a neck condition, a knee condition, a sleepdisorder, a disease, or the like. In some cases, the discomfortexperienced by the user may not be static but may be part of a changingcondition that may have the user experiencing more or less discomfortover time.

In many cases the discomfort the user may experience may be a localdiscomfort such as lower back pain, hip pain, neck pain, shoulder pain,and the like where it may be advantageous to have different firmness inthese areas to provide an improved resting comfort in the localposition. For example, the user may experience lower back pain and theplurality of foam springs 108, with a certain firmness, may beconfigured to provide less firm or firmer support in the lower back areato help provide a comfortable resting position.

In an embodiment, the user's discomfort may change over time, and theplurality of foam springs 108 may be modified to compensate for thechanging user condition. For example, if the user is suffering fromlower back pain, the initial foam spring 108 configuration may providefirmer support in the area of the lower back to position the back forimproved healing. Over time, the user's lower back may improve and thefoam springs 108 firmness in the area of the lower back may be modifiedby gradually providing less firm support until the form spring 108firmness is the same as the remainder of the bed facility 102.

In an embodiment, when considering the location to place the variousfoam spring 108 firmnesses, the user's physical characteristics (e.g.height, weight, body shape, gender) may be considered for the properplacement and firmness of the foam spring 108. For example, theplacement for the foam springs 108 for a user's lower back may beinfluenced by the user's height, typical sleeping position, size of thebed, shape of the bed, location the user sleeps on the bed (e.g. towardsthe head or foot of the bed), and the like.
